[Medico-legal certification of fatal cases after drug: abuse in the light of modern toxicological analysis].

Introduction of modern instrumental methods for toxicological analysis make possible a detection and identification of xenobiotics in different kind of multicomponents biological samples (plant sources of narcotics, body fluids and tissues of abusers) on a low concentration level. In this way a range of possibilities for the interpretation of toxicological results was enlarged. General medicolegal trends are strictly connected with modern analytics and they can be discussed on the basis of drug--users and fatal cases of intoxications with narcotics. Toxicological findings of these cases were worked out by means of modern analytical method--liquid chromatography with mass detection (LC/MS).

[Selected medico-legal problems in cases of poisoning with substances of abuse].

In toxicological examinations of substances of abuse with respect to medico-legal purposes many problems have been discussed. A selection of biological material and proper analytical methods in confrontation with interpretation of results in reference to the subject in question seems to be a central toxicological issue. Blood and urine samples are usually used in cases of human. The problem is more complicated if it concerns dead subjects on the account of postmortem processes in a body. From this point of view, in fatal cases of poisonings experience proves, besides blood and urine also other body fluids such as: cerebrospinal fluid, vitreous humor, perilymph and bile turned out to be usefull for examinations of various xenobiotics. The analytical methods (FPIA, HPLC, GC-MS) have been used for qualitative and quantitative evaluation in wide range of xenobiotic concentration in biological matrix. Interpretation of the results including such problems as toxic interaction, metabolism, data base has been discussed in the study on the basis of intoxication cases with substances of abuse.

ABO(H) group substances in human inner ear fluid.

Tests were carried out on 89 specimens of human inner ear fluid and the results compared with those of blood and salivary gland tests. It was found that ABO(H) group substances are present in the perilymph of secretors.

Gm(1) factor in human inner ear fluid.

The authors carried out investigations on the possibility of determining the Gm(1) factor in endolymph taken from human cadavers, as compared with tests of the blood. No difficulties or anomalies were found in the determination of Gm(1) factor either in the endolymph or the blood taken from cadavers.
